The car is not running but is really clean. I can not work on it for a few month so want to prep it for storage and in the event it sits longer. I have added fuel additive to the 1/4 tank of existing old gas and will turn it over to get the treated gas through the fuel injectors. I would like to drain the gas tank but do not see a drain plug. My 1980s vintage 635 and 325s all had gas tank drain plugs. I completed a search of these forums but did not find and answer. Appreciate some input on whwee it may be located. | | | 02-18-2010, 12:17 AM | #2 | Senior Member Join Date: Apr 2006 Location: Oxford, Ohio Posts: 868 | Like most plastic gas tanks... I don't think there is a drain plug. You will just have to siphon and/or use the fuel pump to pump it out if you are intent on draining it. | | | 03-01-2010, 08:52 PM | #3 | Junior Member Join Date: May 2008 Location: Louisiana Posts: 29 | Hey I went and bought a hand pump from advanced auto, then pulled out the backseats, and unscrewed the fuel pump housing, then pumped all the old gas out. It worked like a charm. | | | 03-01-2010, 09:25 PM | #4 | Junior Member Join Date: Jan 2010 Location: Honolulu, HI Posts: 25 | Fuel tank drain Thanks for the responses. I checked on the BMW parts CD and sure enough it indicated plastic gas tank, whihc I would not expect to find a drain plug. I also came across the blog by the individual who is turing his TI into an electric car, which indicated he ended up cutting the saddle bag style plastic tank in half to pull it out as he did not want to remove the drive line. I think I will disconnect the fuel line at the engine bay, hook up a battery charger to run the fuel pump to drain it.

Rather than removing he decided to cut the tank in half since it was plastic. Apprently he decided he nor anyone else would have use for it. | | | 03-02-2010, 01:48 AM | #8 | Senior Member Join Date: Oct 2009 Location: VIRGINIA Posts: 324 | Quote: Originally Posted by tiFreak | I'm sure it's cool ... but I'm unconvinced about the mileage. I bet I can go further on a tank of petrol than he'll be able to go with a full charge. | | | 03-02-2010, 02:25 AM | #9 | Senior Member Join Date: Oct 2009 Location: VIRGINIA Posts: 324 | A few additional comments: 1. It takes balls to do this to a FUNCTIONING car! 2. Thank goodness it's not a hellrot! 3. Cool? Yes. 4. Practical? Doubtful. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
